Blaine Jones

I have an old family photo of a family in front of a store or restaurant.Above the door it says Jones 1928.On the back it says Uncle Blaine, aunt Hazel and little boy Louis.I can't figure out how this person is related to me, and I'd love some help.I believe that the proper Blaine Jones was born 10 SEpt 1890 in Indiana and died 26 May 1972 in Palm Beach.I believe he was the son of Thomas D Jones and Mary Ann Griffiths.My family, though, is from Iowa and seem unconnected.Who can help me?Is there a library that would love to have my photo?
